When opiates are prescribed by a physician for the treatment of pain and are taken in the prescribed dosage, they are safe and there is little chance of opiate addiction. However, when opiates are abused and taken in excessive doses, opiate addiction can result, leading to a need for rapid detoxification.wo important effects produced by opiates, such as morphine, are pleasure (or reward) and pain relief. The brain itself also produces substances known as endorphins that activate the opiate receptors.
Opioid medications can be natural (made from the plant), semi-synthetic (modified in a lab from the plant), and fully synthetic (completely made by people). Prescription opioids usually come in pill form and are given to treat severe painâfor example, pain from dental surgery, serious sports injuries, or cancer. Opioids are also commonly prescribed to treat other kinds of pain that lasts a long time (chronic pain), but it is unclear if they are effective for long term pain.
